RAC 修改IP：
版本信息：
REDHAT AS5
ORACLE 11G R2, 两个节点。
修改如下：
1.修改/etc/host（rac1,rac2）
192.168.3.205 rac-scan --> 192.168.2.205 192.168.3.201 rac1 --> 192.168.2.201 192.168.3.203 rac2 --> 192.168.2.203
192.168.0.201 rac1-private 192.168.0.203 rac2-private
192.168.3.202 rac1-vip --> 192.168.2.202 192.168.3.204 rac2-vip --> 192.168.2.204
1.关闭服务
./crs_stop -all ./crs_stop ora.DATA.dg ./crs_stop ora.RECOVERY.dg
NAME=ora.RECOVERY.dg TYPE=ora.diskgroup.type TARGET=OFFLINE STATE=ONLINE on rac2
NAME=ora.asm TYPE=ora.asm.type TARGET=OFFLINE STATE=ONLINE on rac2
-------------------------------------------------- [grid@rac1 bin]$ ./srvctl stop asm -n rac1 PRCR-1014 : 无法停止资源 ora.asm PRCR-1065 : 无法停止资源 ora.asm CRS-2673: 尝试停止 'ora.asm' (在 'rac1' 上) ORA-15097: 无法对连接有客户机的 ASM 实例执行 SHUTDOWN CRS-2675: 未能停止 'ora.asm' (在 'rac1' 上)
CRS-2675: 未能停止 'ora.asm' (在 'rac1' 上)
ORA-15097: 无法对连接有客户机的 ASM 实例执行 SHUTDOWN CRS-2675: 未能停止 'ora.asm' (在 'rac1' 上) CRS-2675: 未能停止 'ora.asm' (在 'rac1' 上) 11gr2下，asm是cssd下面管理的要把cssd关掉查，才能关闭asm，在root用户下，执行crs命令，关闭整个crs服务。 [root@rac1 init.d]# find / -name crsctl /opt/rac/11.2.0/grid/bin/crsctl [root@rac1 init.d]#/opt/rac/11.2.0/grid/bin/crsctl stop crs
3.修改IP 并重启网络服务
此步省略
4.使用oifcfg修改网卡设置
[root@rac2 bin]# ./oifcfg getif eth0 192.168.3.0 global public eth1 192.168.0.0 global cluster_interconnect
--删除 [oracle@node1 bin]$ oifcfg delif -global eth0
--添加 [oracle@node1 bin]$ oifcfg setif -global eth0/192.168.2.0:public
(只要在一个节点修改即可)
5. 修改VIP
[root@rac1 bin]# ./srvctl modify nodeapps -n rac1 -A 192.168.2.202/255.255.255.0/eth0
[root@rac2 bin]# ./srvctl modify nodeapps -n rac2 -A 192.168.2.204/255.255.255.0/eth0
6.修改SCAN IP
[root@rac1 bin]# ./srvctl config scan SCAN 名称: rac-scan, 网络: 1/192.168.2.0/255.255.255.0/eth0 SCAN VIP 名称: scan1, IP: /192.168.3.205/192.168.3.205 You have new mail in /var/spool/mail/root [root@rac1 bin]# ./srvctl stop scan_listener [root@rac1 bin]# ./srvctl stop scan [root@rac1 bin]# ./srvctl status scan SCAN VIP scan1 已启用 SCAN VIP scan1 未运行 [root@rac1 bin]# ./srvctl modify scan -n 192.168.2.205 [root@rac1 bin]# ./srvctl config scan SCAN 名称: 192.168.2.205, 网络: 1/192.168.2.0/255.255.255.0/eth0 SCAN VIP 名称: scan1, IP: /rac-scan/192.168.2.205 [root@rac1 bin]#
6.检查状态：
[root@rac1 bin]# ./crs_stat -t

看到还有两个服务没有启动，各自启动：
[root@rac1 bin]# ./crs_start ora.scan1.vip
尝试启动 `ora.scan1.vip` (在成员 `rac2` 上)
启动 `ora.scan1.vip` (在成员 `rac2` 上) 成功。
[root@rac1 bin]# ./crs_start ora.scan2.vip
